With summer just a month or so away OG sandal brand Chaco has teamed up with Philadelphia do-gooders United by Blue for a water-ready lifestyle collection. The limited edition collab includes swim trunks for men and women, as well as sandals for both too, plus UBB’s Summit Convertible Tote.

Each product features special ocean wave-inspired colors and designs. While we’ve sung the praises of the Summit Convertible Tote before—cmon, it’s a backpack and tote bag in one, what’s not to love?—the highlight for us is, no surprise, the men's and women’s sandals, based on the Z/2 Classic Colorado silhouette. The made in USA footwear is sturdy as can be, with a customizable fit and beefy Vibram outsole to provide traction and support in any environment, be it rafting, swimming hole cliff jumping, or just chilling around town.

And as per usual, for every product sold the team behind United by blue physically gets out and removes a pound of trash from oceans and waterways. So support your feet and support protecting where we play and buy some rare collab sandals, OK?
